it is already included in mpfr-impl.h:
$ grep -C 3 LONGLONG_STANDALONE src/mpfr-impl.h
# include "mpfr.h"
# include "mpfr-gmp.h"
# ifdef MPFR_NEED_LONGLONG_H
# define LONGLONG_STANDALONE
# include "mpfr-longlong.h"
# endif
Therefore the issue with undefined sdiv_qrnnd was because the corresponding
code was not protected by #ifdef LONGLONG_STANDALONE?
